Title: Welding seam mfr. on multilayer tubular packaging - has layer compatible with contents welded on inner face of seam to prevent extrusion of chemically impure layers
Inventor: ISLER HANS PETER
IPC: B29C65/50
Filed: 1991-06-28
Abstract: In the mfr. a film strip is folded around a circular mandrel and welded under heat and pressure along the long overlapping edges.
